I was having a hard time with colors and bands so, as it's a Christmas present, i entrusted my wife to do the choosing. This way when i open the box on Christmas morning there will be an element of surprise. The only guidelines I gave her was 45mm, not Nike, and band size 6. 27 years ago she bought me a beautiful watch for Christmas -that I'm wearing now- without my input and i have no reason to think that she'll do at least as good job as I would now.
